What Is the 5-Year Rule for Roth Conversions: Timing and Penalties

The five-year rule for Roth conversions says that each time you move money from a traditional IRA or 401(k) into a Roth IRA, that converted amount has to sit in the Roth for five tax years before you can withdraw it without owing a 10% early withdrawal penalty. Every conversion gets its own clock. The clock only matters if you’re under 59½ when you take the money out.

That’s the whole rule in one paragraph. The details below cover when the clock starts, when it stops mattering, how it interacts with the separate five-year rule on earnings, and the exceptions that let you skip the penalty entirely.

When the Clock Starts and When It Ends

Each conversion’s five-year clock starts on January 1 of the year you did the conversion, not the actual date of the transfer. A conversion completed on December 28, 2025 starts its clock on January 1, 2025, and the converted principal becomes penalty-free on January 1, 2030.1Office of the Law Revision Counsel. 26 U.S. Code 408A – Roth IRAs A late-December conversion effectively buys you almost a full year on the back end.

If you convert money in consecutive years, you’ll have overlapping clocks running at the same time. A 2024 conversion clears January 1, 2029. A 2025 conversion clears January 1, 2030. A 2026 conversion clears January 1, 2031. The IRS treats conversions as withdrawn on a first-in, first-out basis, so when you take money out, the oldest conversion comes out first and the oldest clock is the one that matters.

The Rule Only Matters If You’re Under 59½

This is the detail that most explanations bury. The conversion-specific five-year rule exists to prevent early withdrawals from dodging the 10% penalty. Once you reach 59½, the age-based exception to the 10% penalty overrides the conversion clock entirely. A 62-year-old who converted last year can withdraw that converted principal tomorrow with no penalty.2Office of the Law Revision Counsel. 26 USC 72 – Annuities, Certain Proceeds of Endowment and Life Insurance Contracts

So the people who actually need to track conversion clocks are:

  • Early retirees pulling from retirement accounts before 59½
  • Anyone running a Roth conversion ladder to fund early retirement
  • Backdoor Roth users in their 40s or early 50s who might need the money before 59½

If you’ll be past 59½ when you touch the money, the conversion five-year rule doesn’t apply to you. The earnings rule in the next section still might.

How Withdrawals Come Out of a Roth

Withdrawals from any Roth IRA follow a mandatory order, and it works in your favor:

  • Your regular contributions come out first, always tax-free and penalty-free.
  • Then conversion amounts, oldest first.
  • Earnings come out last.

You empty each tier before touching the next.3Internal Revenue Service. Publication 590-B – Distributions from Individual Retirement Arrangements The five-year rules apply only to the second and third tiers. Your direct contributions are never caught by either clock.

Don’t Let the Custodian Withhold Taxes

When you convert, your IRA custodian may offer to withhold federal taxes from the converted amount. If you’re under 59½, decline. Any amount withheld is treated as a distribution that wasn’t actually converted, which means it’s hit with the 10% early withdrawal penalty on top of the income tax you already owe on the conversion.4Internal Revenue Service. Topic No. 557 – Additional Tax on Early Distributions from Traditional and Roth IRAs Pay the conversion tax from a checking account or other non-retirement money. The full converted amount lands in the Roth and starts compounding tax-free.

The Other Five-Year Rule (For Earnings)

There is a second five-year rule, and people confuse the two constantly. It’s not the same clock, and it’s not the same consequence.

This second rule applies to the whole Roth IRA, not to individual conversions. It controls whether your earnings (investment growth) can be withdrawn tax-free. There’s one clock per person, it starts on January 1 of the year you first funded any Roth IRA by contribution or conversion, and it never resets.1Office of the Law Revision Counsel. 26 U.S. Code 408A – Roth IRAs If you opened your first Roth in 2021, that clock finished on January 1, 2026, and every Roth you open afterward rides on the same start date.

To pull earnings out completely tax-free and penalty-free, two things both have to be true: this five-year clock has finished, and you meet one of these conditions:

  • You’re 59½ or older
  • You’re disabled (medically determinable condition preventing work)
  • First-time home purchase, up to a $10,000 lifetime limit
  • Distribution to a beneficiary or estate after your death

If the five-year clock is done but you miss all those conditions, earnings owe income tax and possibly the 10% penalty. If you’re 59½ but your clock isn’t done, earnings owe income tax but no penalty. That last scenario catches late starters by surprise.

One quirk worth flagging if you have a Roth 401(k): rolling it into a Roth IRA uses the Roth IRA’s clock, not the 401(k)’s. If the receiving Roth IRA is brand new, the earnings clock starts from zero. Opening a Roth IRA with even a small contribution years before you plan to roll over gets that clock running early.

Exceptions That Waive the 10% Penalty

Several exceptions remove the 10% penalty even when the conversion five-year clock isn’t finished. The exception only kills the penalty; if the earnings clock also isn’t satisfied, income tax on any earnings portion still applies.

SEPP deserves extra caution. Once you start, the schedule is rigid. An accidental extra withdrawal or a missed payment triggers a retroactive recapture penalty on every prior distribution in the series.

A Conversion Can’t Be Undone

Before 2018, you could reverse a Roth conversion by recharacterizing it back into a traditional IRA. The Tax Cuts and Jobs Act eliminated that option for any conversion made after December 31, 2017. Once you convert, the tax bill is final and the five-year clock is set in motion. You can still recharacterize a regular Roth contribution as a traditional IRA contribution, but the conversion door only swings one way.

That permanence is the practical reason to think carefully about the size of each conversion and the year you do it. A large conversion stacked on top of a high-income year can push you into a higher tax bracket with no way back. Spreading conversions across lower-income years, such as the gap between leaving work and starting Social Security, keeps the tax cost down and starts smaller clocks earlier.
